Computer A is sending a 10 MByte long file to Computer B via packet-switching over two consecutive 100 Mbps links of 2000 km length each. Assume that the signal propagation speed on both links is 2 x 108 m/s. Furthermore, assume that the maximum length of a packet is 1480 bytes and that Computer A fills each packet to the max, if possible. If transmission starts at time t=0, at which time (in seconds) does the first bit arrive at the switch connecting link 1 and link 2? (What is the propagation delay for link 1?)

This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B. a. Express the propagation delay, dprop, in terms of m and s.b. Determine the transmission time of the packet, dtrans, in terms of L and R.c. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay.d. Suppose Host A begins to transmit the packet at time t = 0.
